Seem to me that the "conclusion" was more or less that even though its ok to use the higher percentage peroxide, why do that and take the risk if its not needed and 3% works " ok" ..
I personally thing a 10% mix would be fine as well ..
Hence the mixing topic.
However, if you want to keep using your existing solution by reactivating it, Then the higher percentage was better as it didnt "water down" the solution you were using.
Sooo 3% to start, 30% ish to reactivate ..
That was the bottom line I got from it.
Which is NOT in the archives that I could find.
And I also did talk to the moderator and in short even though
he agrees that looking in the archives is preferred and makes sense,
that sometimes "newbies" arent sure what terms to use for the search
as they are not that familiar with the whole process, resulting in not getting all the info they need. He didnt otherwise seem to think it was an issue, except to a select few... and I dont think anyone has an abundance of time to read every thread in there.
Just my H O ..
